Add SiloManifestViewer widget that opens in an MDI subwindow when the user double-clicks the Manifest node in the Silo tree. Displays all manifest.json fields in a read-only QFormLayout with copy buttons for Part UUID and Silo Instance. New files: - silo_viewers.py: SiloManifestViewer widget + create_viewer_widget() factory with _VIEWER_REGISTRY for future viewer classes Modified files: - silo_viewproviders.py: doubleClicked() wired to open MDI subwindow with deduplication via widget objectName() - CMakeLists.txt: add silo_viewers.py to install list Closes #38
